The CPU used to be an AMD Phenom X4 955BE until last month. Upgrading my CPU helped my framerate but its still lower than on Windows 7.

The first game i noticed with a reduced framerate was Battlefield 3. On windows 7 with the Phenom i could happily run this game on High and have a stable 60FPS at 1680x1050 but when i moved to 8 i couldn't get over 20FPS no matter what graphics setting i chose. It could be on Ultra or Low but it would still get 20FPS. Since upgrading my CPU to the FX-8350 i now get 40FPS on any graphics setting so there is still an issue.

Another game which has a really terrible framerate is GTA4. I know this is a badly optimised game but it didnt run too badly on 7. With the settings on a mixture of High and Very High i would get 50-60FPS on Windows 7 with the Phenom 955.Now on Windows 8 i get 30FPS with the exact same settings. I even cranked them up to the very max and got 28FPS. I did not test GTA4 on the Phenom on Windows 8 so it could be CPU related but i highly doubt it.

The strangest game to show issues is Worms Revolution. This is the new worms that has a 3D look to it and has some niec 3D backgrounds but remaining its 2D-style gameplay. I used to play this at a full framerate on Windows 7 with my Phenom but as soon as i changed to Windows 8 it is truely unplayable, the framerate doesnt go above 5 and the gameplay is very juddery. Even the FX-8350 didn't help this

There are quite a few games which have seen reduced performance since Windows 8 and its really a shame since everythign else is nice and quick. Some games don't seem to be affected and have the same framerate as Win7 such as ARMA2 and Dirt Showdown which is strange.

Just to clarify, i am using the latest beta drivers but i was using 12.10 first. 12.11 did help the framerate in BF3 slightly. Anything i can do to try and get playable framerates in these games or will i have to wait until the next driver?

The biggest problem in Windows 8 is that it's not NEW. It's built off of Vista, same as 7, and just isn't innovative. The move from XP to Vista was massive, plenty of new things, plenty of annoyances (UAC anyone?), but with 7 and now 8 it's been nVidia 8800 all over again. Name one thing in Windows 8 that is new and innovative? Can't say the Windows 8 UI (can't say Metro) because it was used in phones. Can't say the native mounting of disk images, that's just integrating what Daemon Tools and several other programs have been able to do for years as addon software. It's not faster, it's not more lean, it's just Windows 7 sans DVD playback capabilities.

But as for the game problems, could it be that the games just need to be patched to work correctly with Windows 8. Hmm...

One thing I can say with certainty, for 50bucks this was a worthy upgrade from Vista.As for drivers, no issues now, everything working as it's supposed to. And, only one program that doesn't behave quite right (incredimail) so waiting on their Win8 update.Back on topic all games still work fine, but then again I'm not an FPS nut, keep vsync on, and really haven't noticed any change.

I haven't seen one, but, the author of the article currently refers to Win8 as equal to or better than Win7 for gaming. That was a old article that had many good points...mainly, don't expect a new OS to be perfect at first.
